If you are looking to experience more of what Belize is really like, and to get to know the locals, this is a great place to start. Plenty of beach clubs nearby if you want some good food and pampering but also close to good local restaurants and shopping.
We really enjoyed both the Placencia Beach Club and the Umaya Resort. We ate and drank all day at PBC for about $40USD PP. Wish we had tried Umaya sooner because it was a great place to spend the day. Plenty of signs saying beach and pool for guests only, but as long as you are spending $$ (and they aren't really busy) staff doesn't care. Jauguar Lanes across the street has solid pizza and drinks and was a good home base for us. Good mix of locals and expats made for a fun vibe.
We did a Daytripper boat excursion with snorkeling and had a great time. Staff was fun and the lunch and rum punch were better than we anticipated. If you've never snorkeled before, take a class on your own or practice first because there wasn't any instruction beforehand. Not a big deal for our group, but for a group of beginners it might make it less enjoyable.
The house itself was exactly like the pictures and was clean and comfortable with a very nice beach view with plenty of breeze. We spent every morning and evening on the deck talking and listening to the waves. Owners prepare you well for your visit with a handy info guide. We only had one minor issue while there but the property manager was on it instantly. Overall, great house!
